I have my twitch account linked but i still cannot stream my minecraft - It says Unavailable

Please Help ME!!!!
So as it says: Link your twitch account- Did that
Now it tells me "Twitch Broadcasting Unavailable"
and when I press F6 (the streaming shortcut) It tells me the exact same thing! please tell me whats going on! I really want to stream and check out the new feature but its being retarded!
